Grant-Kohrs Ranch National Historic Site

Grant-Kohrs Ranch National Historic Site is off I-90 exit 184 or 187. Established in the early 1860s, the ranch had grown to 27,000 acres by the early 1900s, and the owners controlled more than a million acres of public range in four states and Canada. Though much reduced, the 1,500-acre ranch still has livestock and more than 80 buildings, from bunkhouse row to the 23-room ranch house.

Guided tours are available.
